The Sales Analyzer page gives you an overview over your sales history. There are some stats for recent profits and gains as well as a prediction of future profits based on the current performance of your bot.
Note: In order to have a full sales history you have to set the Profit Trailer setting for the trading log history accordingly. Just set the value for trading.logHistory in your application.properties to 9999 to make sure Profit Trailer does not remove entries from your Sales Log after some days.
